[Treatment of rheumatoid polyarthritis with methotrexate in Dakar: efficacy, tolerance and cost].

Methotrexate (MTX), which has been used for years in cancer treatment, is now being proposed as a first-line treatment for rheumatoid arthritis (RA), despite its potential side effects. The aim of this study was to investigate the short-term efficacy, safety and relative cost of low-dose MTX for the treatment of RA. We carried out an open, nonrandomized trial in which patients received a 7 mg injection of MTX once per week, with clinical and biological follow up. A single physician performed the weekly assessments, which involved evaluation of the duration of morning stiffness, the number of night awakenings, the number of painful and swollen joints and Ritchie's index. Blood cell count and erythrocyte sedimentation rate were determined monthly. Twelve RA patients were enrolled in the trial, over a mean treatment period of 356 +/- 175 days. A significant improvement was observed in all variables except the number of swollen joints. Ritchie's index decreased from a mean of 31.8 +/- 11.85 to 6.5 +/- 8.98 (p<1.6 x 10- 4). Minor adverse reactions were observed but none indicated treatment withdrawal: 6 cases of nausea, 2 of a moderate increase in transaminase activity, 1 of bronchitis, in which the responsibility of MTX was not definitely established and 3 cases in which hemoglobin levels decreased. The monthly cost of the treatment, including the drug itself and laboratory tests, is lower than that of gold salt injection. Three issues of key importance in our region were investigated in this study: 1) the possible desire to become pregnant of female patients undergoing MTX treatment. In addition, some of the young and unmarried patients did not understand or appreciate the contraceptive effects of the treatment; 2) poor compliance with the treatment due to limited financial resources. Many patients did not regularly attend for their follow-up appointments and many stopped taking the medication. One third of the patients were lost to follow-up during this study; 3) the prevalence of chronic hepatitis, which may limit the use of MTX in our region. Serological tests should be performed before the treatment is started and a liver biopsy is recommended for patients with chronic hepatitis B or C.

[Practical problems encountered in the multi-drug therapy of leprosy in Senegal].

The authors make an inventory of the difficulties they have met while realizing the different stages of MDT treatment programmes in Senegal. Main problems were: Necessity of complementary training on theoretical, but even more on practical techniques for all the staff: Ridley and Jopling classification, neurological examination, bacteriological examination, data collection. Difficulty to maintain a true supervision. Necessity to settle a quality control of slit skin smears. Necessity to settle a system to trace irregular patients. Heaviness of centralized management, but its necessity to maintain "tightness" of the drugs distribution network. Difficulty to obtain a regular follow up of patients who are released for treatment. The evolution of anti-leprosy activities makes it necessary to adapt the "Service des Grandes Endémies".

[A trial of polychemotherapy of leprosy in the Dakar region. Initial observations on the acceptability of the protocols used].

Since 1982, in Dakar, a controlled essay tests the suitability of several short protocols of multidrug therapy (MDT), some of them being close to those advised by the WHO, others showing a starter stage of a two month daily MDT. In three years, 198 paucibacillary and 123 multibacillary patients have been treated. The short duration of these treatments leads to an important decrease in the load of the Department. The total rate of those who have not attended for the treatment is of 15.2% whereas it was of 52% with DDS monotherapy for a similar treatment duration. Those who gave up don't seem to live in Dakar. To judge by the diligence of the patients, the compliance seems excellent even for the protocols requiring a daily dose of ethionamide: 95% of paucibacillary, 76% of multibacillary patients have maximal attendance. The authors think that any MDT program: must be preceded by a retraining of staffs; must give a priority to the health education of the patients; must involve a home patient search for system.

[Prevention of perforating plantar ulcers: trial directed by a mobile team].

AIMS: to prevent the appearance of plantar ulcerations and then mutilations, by going in the field in order to: make suitable footwear, educate the patients, train the paramedical staff. Means: 1 fitted lorry, 1 physiotherapist, 1 shoemaker, and 1 educator. RESULTS: In one year, 206 patients have been provided with shoes and followed up. Advice have been taken exactly in the leper villages in which the attendance rate is of 98%; this rate varies between 47 to 70% in the all-purpose dispensaries. Paramedical workers of all-purpose Health Centers did not take great interest in this action. After 6-12 months under observation: 84% of good results for the feet without deformity or slightly deformed; 51% for the deformed feet. The results are quite satisfactory for the feet without plantar ulcer at the beginning, and that whatever the food deformity stage. But for the feet wounded by plantar ulcer at the beginning, 33% of recovery have been reported after wearing these shoes.

Systemic lupus erythematosus and lupus syndromes in Senegal. A retrospective study of 30 patients seen over 10 years.

OBJECTIVE: To define the presenting manifestations, course and prognosis of systemic lupus erythematosus in Senegal. PATIENTS AND METHODS: Thirty cases of systemic lupus erythematosus and lupus syndromes seen over a ten-year period were reviewed retrospectively. Nineteen patients met American College of Rheumatology criteria for systemic lupus erythematosus. All 30 patients were Senegalese-born black women. Mean age at diagnosis was 30 years (range, 16-73 years). RESULTS: Polyarthritis was the most common presenting picture (n = 8), followed by discoid lupus (n = 6). Eight per cent of patients had at least a combination of skin and joint symptoms at diagnosis. Prevalences of organ involvement were as follows: skin, 97%; joints, 97%; kidneys, 57%; serous membranes, 43%; nervous system, 23% and blood, 83%. Mean symptom duration at diagnosis was 24 months in systemic lupus erythematosus patients and 43 months in lupus syndrome patients. This significant diagnostic delay explains why as many as five of the 30 patients (17%) died either before or within five months of treatment initiation. Eight patients (32% of treated patients) who had a favorable course under therapy were lost to follow-up after discharge. The overall mortality rate was 26%. Renal failure was the main cause of death, followed by infectious and neurologic complications. CONCLUSION: We anticipate that the reported prevalence of lupus in Senegal will rise in the near future as a result of improvements in diagnostic tools and of increased interest for lupus among physicians. We also hope that improved detection of mild and early forms, together with close long-term follow-up of patients, will translate into a better overall prognosis.
